Comparison of the infrapatellar and subcutaneous adipose tissue biopsy material as a source of mesenchymal stromal cells for regenerative medicine in traumatology
Objective. The use of infrapatellar fat pad (IPFP) as the source of mesenchymal stem cells (MSCs), show an age-independent proliferation and differentiation potential. In addition, the pronounced chondrogenic potential of IPFP-ASCs makes them promising candidates for research for use in other methodsof regenerative therapy. Methods. A direct immunohistochemical study was carried out in serial paraffin sections of the biopsy material of Hoffa`s fat pad and subcutaneus fat tissue, using monoclonal antibodies. The minimum criteria established by the International Society for Cell Therapy to ensure the identity of MSCs use CD73 and CD105 as positive markers and CD34, CD31, CD45 as a negative. Results. According to the results of histological, immunohistochemical, morphometric and statistical studies, it was found that in the biopsy of both tissues the relative number of cells with an immunoprofile CD105+, CD73+, CD34–, CD31–, CD45– in the standard field of view (×200) was: 7.25 (5.42; 8.89 ) %, and 11.11 (8.46; 13.45) %, no statistically significant difference was found between comparison groups (р > 0,05). Conclusion. The therapeutic effect of mesenchymal stem cells of subcutaneous adipose tissue has been proven, thus the identification of similar cells in the biopsy material and relatively similar density in the Hoffa body makesit an important source of adipose-derived stem cells that can be used for regenerative engineering tissue.
